2009-06-06daemon: Strictly parse the "extra arg" part of the commandLibravatar Shawn O. Pearce1-1/+4
Since 1.4.4.5 (49ba83fb67 "Add virtualization support to git-daemon") git daemon enters an infinite loop and never terminates if a client hides any extra arguments in the initial request line which is not exactly "\0host=blah\0". Since that change, a client must never insert additional extra arguments, or attempt to use any argument other than "host=", as any daemon will get stuck parsing the request line and will never complete the request. Since the client can't tell if the daemon is patched or not, it is not possible to know if additional extra args might actually be able to be safely requested. If we ever need to extend the git daemon protocol to support a new feature, we may have to do something like this to the exchange: # If both support git:// v2 # C: 000cgit://v2 S: 0010ok host user C: 0018host git.kernel.org C: 0027git-upload-pack /pub/linux-2.6.git S: ...git-upload-pack header... # If client supports git:// v2, server does not: # C: 000cgit://v2 S: <EOF> C: 003bgit-upload-pack /pub/linux-2.6.git\0host=git.kernel.org\0 S: ...git-upload-pack header... This requires the client to create two TCP connections to talk to an older git daemon, however all daemons since the introduction of daemon.c will safely reject the unknown "git://v2" command request, so the client can quite easily determine the server supports an older protocol.

2009-04-25connect: replace inet_ntop with getnameinfoLibravatar Benjamin Kramer1-11/+4
inet_ntop is not protocol independent. getnameinfo(3) is part of POSIX and is available when getaddrinfo(3) is. This code is only compiled when NO_IPV6 isn't defined. The old method was buggy anyway, not every ipv6 address was converted properly because the buffer (addr) was too small.

2009-03-10connect.c: remove a few globals by using git_config callback dataLibravatar Erik Faye-Lund1-6/+3
Since ef90d6d (Provide git_config with a callback-data parameter, 2008-05-14), git_config() takes a callback data pointer that can be used to pass extra parameters to the parsing function. The codepath to parse configuration variables related to git proxy predates this facility and used a pair of file scope static variables instead. This patch removes the need for these global variables by passing the name of the host we are trying to access as the callback data.

2008-11-02connect.c: add a way for git-daemon to pass an error back to clientLibravatar Tom Preston-Werner1-0/+3
The current behavior of git-daemon is to simply close the connection on any error condition. This leaves the client without any information as to the cause of the failed fetch/push/etc. This patch allows get_remote_heads to accept a line prefixed with "ERR" that it can display to the user in an informative fashion. Once clients can understand this ERR line, git-daemon can be made to properly report "repository not found", "permission denied", or other errors. Example S: ERR No matching repository. C: fatal: remote error: No matching repository. Signed-off-by: Tom Preston-Werner <tom@github.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

With all calls to alloc_ref() gone, we can remove it and then we're free to give alloc_ref_from_str() the shorter name. It's a much nicer interface, as the callers always need to have a name string when they allocate a ref anyway and don't need to calculate and pass its length+1 any more.

2008-09-09push: prepare sender to receive extended ref information from the receiverLibravatar Junio C Hamano1-1/+15
"git push" enhancement allows the receiving end to report not only its own refs but refs in repositories it borrows from via the alternate object store mechanism. By telling the sender that objects reachable from these extra refs are already complete in the receiving end, the number of objects that need to be transfered can be cut down. These entries are sent over the wire with string ".have", instead of the actual names of the refs. This string was chosen so that they are ignored by older programs at the sending end. If we sent some random but valid looking refnames for these entries, "matching refs" rule (triggered when running "git push" without explicit refspecs, where the sender learns what refs the receiver has, and updates only the ones with the names of the refs the sender also has) and "delete missing" rule (triggered when "git push --mirror" is used, where the sender tells the receiver to delete the refs it itself does not have) would try to update/delete them, which is not what we want. This prepares the send-pack (and "push" that runs native protocol) to accept extended existing ref information and make use of it. The ".have" entries are excluded from ref matching rules, and are exempt from deletion rule while pushing with --mirror option, but are still used for pack generation purposes by providing more "bottom" range commits.

2008-02-22Avoid unnecessary "if-before-free" tests.Libravatar Jim Meyering1-2/+1
This change removes all obvious useless if-before-free tests. E.g., it replaces code like this: if (some_expression) free (some_expression); with the now-equivalent: free (some_expression); It is equivalent not just because POSIX has required free(NULL) to work for a long time, but simply because it has worked for so long that no reasonable porting target fails the test. Here's some evidence from nearly 1.5 years ago: http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html FYI, the change below was prepared by running the following: git ls-files -z | xargs -0 \ perl -0x3b -pi -e \ 's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s' Note however, that it doesn't handle brace-enclosed blocks like "if (x) { free (x); }". But that's ok, since there were none like that in git sources. Beware: if you do use the above snippet, note that it can produce syntactically invalid C code. That happens when the affected "if"-statement has a matching "else". E.g., it would transform this if (x) free (x); else foo (); into this: free (x); else foo (); There were none of those here, either. If you're interested in automating detection of the useless tests, you might like the useless-if-before-free script in gnulib: [it *does* detect brace-enclosed free statements, and has a --name=S option to make it detect free-like functions with different names] http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free Addendum: Remove one more (in imap-send.c), spotted by Jean-Luc Herren <jlh@gmx.ch>.

However, for the git:// protocol, there is no need to have another process, so the return value was NULL.

2007-09-29bundle transport: fix an alloc_ref() callLibravatar Junio C Hamano1-2/+2
Currently alloc_ref() expects the length of the refname plus 1 as its parameter, prepares that much space and returns a "ref" structure for the caller to fill the refname. One caller in transport.c::get_refs_from_bundle() however allocated one byte less. It may be a good idea to change the calling convention to give alloc_ref() the length of the refname, but that clean-up can be done in a separate patch. This patch only fixes the bug and makes all callers consistent. There was also one overallocation in connect.c, which would not hurt but was wasteful. This patch fixes it as well.

2007-06-06introduce GIT_WORK_TREE to specify the work treeLibravatar Matthias Lederhofer1-0/+1
setup_gdg is used as abbreviation for setup_git_directory_gently. The work tree can be specified using the environment variable GIT_WORK_TREE and the config option core.worktree (the environment variable has precendence over the config option). Additionally there is a command line option --work-tree which sets the environment variable. setup_gdg does the following now: GIT_DIR unspecified repository in .git directory parent directory of the .git directory is used as work tree, GIT_WORK_TREE is ignored GIT_DIR unspecified repository in cwd GIT_DIR is set to cwd see the cases with GIT_DIR specified what happens next and also see the note below GIT_DIR specified GIT_WORK_TREE/core.worktree unspecified cwd is used as work tree GIT_DIR specified GIT_WORK_TREE/core.worktree specified the specified work tree is used Note on the case where GIT_DIR is unspecified and repository is in cwd: GIT_WORK_TREE is used but is_inside_git_dir is always true. I did it this way because setup_gdg might be called multiple times (e.g. when doing alias expansion) and in successive calls setup_gdg should do the same thing every time. Meaning of is_bare/is_inside_work_tree/is_inside_git_dir: (1) is_bare_repository A repository is bare if core.bare is true or core.bare is unspecified and the name suggests it is bare (directory not named .git). The bare option disables a few protective checks which are useful with a working tree. Currently this changes if a repository is bare: updates of HEAD are allowed git gc packs the refs the reflog is disabled by default (2) is_inside_work_tree True if the cwd is inside the associated working tree (if there is one), false otherwise. (3) is_inside_git_dir True if the cwd is inside the git directory, false otherwise. Before this patch is_inside_git_dir was always true for bare repositories. When setup_gdg finds a repository git_config(git_default_config) is always called. This ensure that is_bare_repository makes use of core.bare and does not guess even though core.bare is specified. inside_work_tree and inside_git_dir are set if setup_gdg finds a repository. The is_inside_work_tree and is_inside_git_dir functions will die if they are called before a successful call to setup_gdg.

2007-03-27Fix "getaddrinfo()" bugletLibravatar Linus Torvalds1-1/+3
At least in Linux glibc, "getaddrinfo()" has a very irritating feature (or bug, who knows..). Namely if you pass it in an empty string for the service name, it will happily and quietly consider it identical to a NULL port pointer, and return port number zero and no errors. Which obviously will not work. Maybe that's what it's really expected to do, although the man-page for getaddrinfo() certainly implies that it's a bug. So when somebody passes me a "please pull" request pointing to something like the following git://git.kernel.org:/pub/scm/linux/kernel/git/mchehab/v4l-dvb.git (note the extraneous colon at the end of the host name), git would happily try to connect to port 0, which would generally just cause the remote to not even answer, and the "connect()" will take a long time to time out. So to work around the glibc feature/bug, just notice this empty port case automatically. Also, add the port information to the error information when it fails to look up (maybe it's the host-name that fails, maybe it's the port-name - we should print out both).

2007-01-21Make sure git_connect() always give two file descriptors.Libravatar Junio C Hamano1-1/+1
Earlier, git_connect() returned the same fd twice or two separate fds, depending on the way the connection was made (when we are talking to the other end over a single socket, we used the same fd twice, and when our end is connected to a pipepair we used two). This forced callers who do close() and dup() to really care which was which, and most of the existing callers got this wrong, although without much visible ill effect. Many were closing the same fd twice when we are talking over a single socket, and one was leaking a fd. This fixes it to uniformly use two separate fds, so if somebody wants to close only reader side can just do close() on it without worrying about it accidentally also closing the writer side or vice versa.

This changes the refname matching logic used to decide which ref is updated with git-send-pack. We used to error out when pushing 'master' when the other end has both 'master' branch and a tracking branch 'remotes/$name/master' but with this, 'master' matches only 'refs/heads/master' when both and no other 'master' exist. Pushing 'foo' when both heads/foo and tags/foo exist at the remote end is still considered an error and you would need to disambiguate between them by being more explicit. When neither heads/foo nor tags/foo exists at the remote, pushing 'foo' when there is only remotes/origin/foo is not ambiguous, while it still is ambiguous when there are more than one such weaker match (remotes/origin/foo and remotes/alt/foo, for example).

2006-09-12connect.c: finish_connect(): allow null pid parameterLibravatar Franck Bui-Huu1-2/+11
git_connect() can return 0 if we use git protocol for example. Users of this function don't know and don't care if a process had been created or not, and to avoid them to check it before calling finish_connect() this patch allows finish_connect() to take a null pid. And in that case return 0.

2006-09-10Fix a memory leak in "connect.c" and die if command too long.Libravatar Christian Couder1-3/+14
Use "add_to_string" instead of "sq_quote" and "snprintf", so that there is no memory allocation and no memory leak. Also check if the command is too long to fit into the buffer and die if this is the case, instead of truncating it to the buffer size.

2006-09-05send-pack: remove remote reference limitLibravatar Andy Whitcroft1-1/+1
When build a pack for a push we query the remote copy for existant heads. These are used to prune unnecessary objects from the pack. As we receive the remote references in get_remote_heads() we validate the reference names via check_ref() which includes a length check; rejecting those >45 characters in size. This is a miss converted change, it was originally designed to reject messages which were less than 45 characters in length (a 40 character sha1 and refs/) to prevent comparing unitialised memory. check_ref() now gets the raw length so check for at least 5 characters.

2006-09-02Replace uses of strdup with xstrdup.Libravatar Shawn Pearce1-3/+3
Like xmalloc and xrealloc xstrdup dies with a useful message if the native strdup() implementation returns NULL rather than a valid pointer. I just tried to use xstrdup in new code and found it to be missing. However I expected it to be present as xmalloc and xrealloc are already commonly used throughout the code.

2006-08-23Convert memcpy(a,b,20) to hashcpy(a,b).Libravatar Shawn Pearce1-3/+3
This abstracts away the size of the hash values when copying them from memory location to memory location, much as the introduction of hashcmp abstracted away hash value comparsion. A few call sites were using char* rather than unsigned char* so I added the cast rather than open hashcpy to be void*. This is a reasonable tradeoff as most call sites already use unsigned char* and the existing hashcmp is also declared to be unsigned char*. [jc: Splitted the patch to "master" part, to be followed by a patch for merge-recursive.c which is not in "master" yet. Fixed the cast in the latter hunk to combine-diff.c which was wrong in the original. Also converted ones left-over in combine-diff.c, diff-lib.c and upload-pack.c ] Signed-off-by: Shawn O.

2006-08-15finish_connect(): thinkofixLibravatar Junio C Hamano1-8/+3
All but one callers have ignore the return value from this function, but the only caller, builtin-tar-tree.c::remote_tar(), assumed it returns non-zero on failure and zero on success. The implementation however was returning either the waited pid (which must be the same as its input) or -1 (an error). Fix this thinko, while getting rid of an assignment of return value from waitpid() into a variable of type int. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-07-04Improve git-peek-remoteLibravatar Linus Torvalds1-4/+31
This makes git-peek-remote able to basically do everything that git-ls-remote does (but obviously just for the native protocol, so no http[s]: or rsync: support). The default behaviour is the same, but you can now give a mixture of "--refs", "--tags" and "--heads" flags, where "--refs" forces git-peek-remote to only show real refs (ie none of the fakey tag lookups, but also not the special pseudo-refs like HEAD and MERGE_HEAD). The "--tags" and "--heads" flags respectively limit the output to just regular tags and heads, of course. You can still also ask to limit them by name too. You can combine the flags, so git peek-remote --refs --tags . will show all local _true_ tags, without the generated tag lookups (compare the output without the "--refs" flag). And "--tags --heads" will show both tags and heads, but will avoid (for example) any special refs outside of the standard locations. I'm also planning on adding a "--ignore-local" flag that allows us to ask it to ignore any refs that we already have in the local tree, but that's an independent thing. All this is obviously gearing up to making "git fetch" cheaper. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
